Gardeners' Notes:

This tree does fairly well in Zone 7b. So much so that a local Christmas tree farm relies heavily on Concolors for much of their stock. My own experience has been clear cut. White firs planted amongst large pines do not survive, but they do outstanding when planted almost anywhere else. I do believe this is due to the higher acidic level near pines (particularly some of my full grown Virginia pines). Concolors seem to prefer more neutral to alkaline soils. I am open to being quite wrong about this however.
